The pin mechanism includes a pin, the pin being offset from the axis of rotation of the rotatable knob. The slider body is shaped to include a slot in which the pin of the pin mechanism is positioned and a switch recess shaped to receive and selectively contact the switch of the electronic device. Rotation of the rotatable knob in a first direction causes the slider body toward contact with a first portion of the switch to urge the switch into a first position, and rotation of the rotatable knob in a second direction causes the slider body toward contact with a second portion of the switch to urge the switch into a second position.

CROSS-REFERENCE TO RELATED APPLICATIONS

The present application is a continuation of U.S. patent application Ser. No. 16/557,364, filed Aug. 30, 2019, the entirety of which is herein incorporated by reference.

TECHNICAL FIELD

The present specification generally relates to protective cases that cover electronic devices and, more specifically, cases that have a switch assembly for engaging a switch of an electronic device.

BACKGROUND

As background, electronic devices (e.g., smartphones, tablets, or the like) generally include switches to control various functionality of the device. For example, a switch may include a muting switch that turns off the volume of the mobile device, particularly to silence a ringtone. In order to provide additional protection against falls or fluid contact, protective cases may be arranged around the device while still allowing functional access to the screen and/or buttons of the device. Certain protective cases may include an opening around a switch to allow for direct user access to the sliding switch. However, direct access may inadvertently provide an entry point for fluid into the mobile device, which may lead to water damage. Other protective cases may include a protective switch that covers and engages with the switch of the mobile device such that the protective switch is actuable by a user to move in the same manner as the switch and move the switch. However, direct manipulation of such protective sliding switches may be difficult for some users.

SUMMARY

In one aspect, a switch assembly for engaging a switch of an electronic device includes a rotatable knob having an axis of rotation, a pin mechanism engaged with the rotatable knob, and a slider body. The pin mechanism includes a pin, the pin being offset from the axis of rotation of the rotatable knob. The slider body is shaped to include a slot in which the pin of the pin mechanism is positioned and a switch recess. The switch recess is shaped to receive and selectively contact the switch of the electronic device when the electronic device is positioned proximate the slider body. Rotation of the rotatable knob in a first direction causes the pin to travel in the slot in a first direction and move the slider body toward contact with a first portion of the switch to urge the switch into a first position, and rotation of the rotatable knob in a second direction causes the pin to travel in the slot in a second direction and move the slider body toward contact with a second portion of the switch to urge the switch into a second position.

In another aspect, a protective case for an electronic device includes a frame shaped to receive the electronic device therein and a switch assembly coupled to the frame for engaging a switch of the electronic device. The switch assembly includes a rotatable knob having an axis of rotation, a pin mechanism engaged with the rotatable knob, and a slider body. The pin mechanism includes a pin, the pin being offset from the axis of rotation of the rotatable knob. The slider body is shaped to include a slot in which the pin of the pin mechanism is positioned and a switch recess. The switch recess is shaped to receive and selectively contact the switch of the electronic device when the electronic device is positioned proximate the slider body. Rotation of the rotatable knob in a first direction causes the pin to travel in the slot in a first direction and move the slider body toward contact with a first portion of the switch to urge the switch into a first position, and rotation of the rotatable knob in a second direction causes the pin to travel in the slot in a second direction and move the slider body toward contact with a second portion of the switch to urge the switch into a second position.

In yet another aspect, a protective case for an electronic device includes a frame having a front portion and a back portion coupled together to define a cavity shaped to receive and encapsulate the electronic device having a switch, and a switch assembly positioned on one of the front portion or the back portion of the frame for engaging the switch of the electronic device when the electronic device is positioned in the cavity defined by the front portion and the back portion. The switch assembly includes a rotatable knob having an axis of rotation, a pin mechanism engaged with the rotatable knob, and a slider body. The pin mechanism includes a pin, the pin being offset from the axis of rotation of the rotatable knob. The slider body is shaped to include a slot in which the pin of the pin mechanism is positioned and a switch recess. The switch recess is shaped to receive and selectively contact the switch of the electronic device when the electronic device is positioned proximate the slider body. Rotation of the rotatable knob in a first direction causes the pin to travel in the slot in a first direction and move the slider body toward contact with a first portion of the switch to urge the switch into a first position, and rotation of the rotatable knob in a second direction causes the pin to travel in the slot in a second direction and move the slider body toward contact with a second portion of the switch to urge the switch into a second position.

These and additional features provided by the embodiments described herein will be more fully understood in view of the following detailed description, in conjunction with the drawings.

DETAILED DESCRIPTION

The figures generally depict a protective case with an integrated switch assembly for engaging a switch of an electronic device. Switch assemblies according to the present disclosure may include a rotatable knob having an axis of rotation, a pin mechanism, and a slider body. The pin mechanism is engaged with the rotatable knob and includes a pin that is offset from an axis of rotation of the rotatable knob. The slider body may be shaped to include a slot in which the pin of the pin mechanism may be positioned. The slider body may further be shaped to include a switch recess that is shaped to receive and selectively contact the switch of the electronic device when the electronic device is positioned proximate the slider body. Rotation of the rotatable knob in a first direction may cause the pin to travel in the slot in a first direction and move the slider body toward contact with a first portion of the switch to urge the switch into a first position (e.g., an active or enabled position). Rotation of the rotatable knob in a second direction may cause the pin to travel in the slot in a second direction and move the slider body toward contact with a second portion of the switch to urge the switch into a second position (e.g., a deactivated or disabled position). Such switch assembly allows for a switch of an electronic device to be completely enclosed, to prevent ingress of fluid and/or debris, without limiting operation of the switch. Additionally, the present devices provides an easier and more comfortable way to engage the switch of the electronic device. Various embodiments of the switch assembly and protective case will be described in more detail herein.

An electronic device may include any electronic device such as a pager, PDA, cellphone, smart phone, tablet, laptop, or the like. Electronic devices according to the present disclosure may include a switch (e.g., a sliding switch, such as a muting switch). It is noted that a switch may be a switch that slides or toggles from a first position to a second position. As will be described herein, an electronic device may be positioned within the protective case. The protective case may provide a protective, and/or waterproof housing around the mobile the device.

Referring now to FIGS. 1A and 1B, an embodiment of a protective case 10 is generally depicted. The protective case 10 generally includes a frame 12. The frame 12 defines a cavity 11 within which an electronic device may be disposed. The frame 12 may be separable into one or more components to allow for insertion of the electronic device into the cavity 11 defined by the frame 12. For example, the frame 12 may include a front portion 14, illustrated in FIG. 1A and a back portion 16, illustrated in FIG. 1B. It is noted that each of the front portion 14 and the back portion 16 may be single integral articles or may be assemblies of sub-frame components.

The front portion 14 and the back portion 16 may be separably coupled to one another. That is, the front portion 14 may be assembled to and disassembled from the back portion 16 repeatedly (e.g., to allow for insertion and removal of the electronic device). When the front portion 14 is assembled to the back portion 16 around an electronic device, a fluid tight seal (e.g., a watertight seal and/or an airtight seal) may be formed between the front portion 14 and the back portion 16 to prevent ingress or egress of liquid, dirt, or other debris, into the protective case 10, thereby protecting the electronic device from contact with liquid, dirt, or debris. That is, the protective case 10, when assembled, may provide a waterproof housing for the electronic device positioned therein.

The back portion 16 of the frame 12 may have a body 13 that is arranged to correspond to one or more features of a backside of an electronic device when the electronic device is received within the cavity 11 of the protective case 10. For example, the back portion 16 of the frame 12 may include one or more camera windows 17 or apertures that are aligned with one or more components of a camera device (e.g., a lens and/or flash) to allow for the capture of images by the electronic device when the electronic device is positioned within the protective case 10. In addition, the back portion 16 of the frame 12 may be shaped and sized to generally correspond to the shape and size of a particular electronic device such that the electronic device, when received in the protective case 10 fits within the cavity 11 defined by the frame 12.

The back portion 16 may include one or more projections 15 extending from the body 13 of the back portion 16. The one or more projections 15 are receivable by one or more receiving apertures 20 in the front portion 14 to couple the front portion 14 to the back portion 16, the one or more receiving apertures 20 corresponding in shape and size to the one or more projections 15 such that the one or more receiving apertures 20 retain the one or more projections 15 when the back portion 16 is joined with the front portion 14, as described herein. For example, the back portion 16 may include a plurality of projections disposed around a perimeter of the back portion 16 of the case. In other embodiments, the one or more projections 15 may be part of the front portion 14 of the frame 12 and the one or more receiving apertures 20 may be formed in the back portion 16 of the frame 12.

The front portion 14 of the frame 12 may be have a body 23 arranged to correspond to one or more features of a front side of an electronic device when the electronic device is received within the cavity 11 of the protective case 10. For example, the front portion 14 of the frame 12 may include a screen aperture 21 that is aligned within one or more portions of a touch screen or other user input hardware of the electronic device to allow for interaction of a user with the touch screen or other user input hardware. In some embodiments, the screen aperture 21 may include a protective screen made of plastic, glass, or any other suitable material. In addition, the front portion 14 of the frame 12 may be shaped and sized to generally correspond to the shape and size of a particular electronic device such that the electronic device, when received in the protective case 10 fits within the cavity 11 defined by the frame 12.

The front portion 14, the back portion 16, or a combination thereof may define a sidewall 22 of the frame 12. The sidewall 22 may be arranged to correspond to a perimeter of the electronic device when the electronic device is positioned within the frame 12. The sidewall 22 may define an interior side 64 and an exterior side 68, wherein the electronic device is position on an interior side 64 of the sidewall 22 when positioned within the frame 12. Formed within the sidewall 22 may be an assembly port 24 (further illustrated in FIGS. 2A-4B) to which a switch assembly 100 may be assembled.

That is, coupled to the frame 12 at an assembly port 24 is a switch assembly 100 for engaging a switch 52 of an electronic device 50, as illustrated in FIGS. 4A and 4B. The switch assembly 100 encloses around the switch 52 of the electronic device 50, and when actuated, allows the switch assembly 100 to selectively contact the switch 52 to engage and disengage a function of the switch 52 by moving the switch 52 from an active position to an inactive position and vice versa.

FIGS. 2A-2C illustrate various exploded views of the switch assembly 100 from the sidewall 22 of the frame 12. The various portions of the assembly port 24 will be further described in relation to the various components of the switch assembly 100 mounted to the assembly port 24. In particular, the switch assembly 100 generally includes a rotatable knob 102, a pin mechanism 160, and a slider body 170 mounted to the frame 12 via the assembly port 24. The assembly port 24 may define one or more recesses for receiving and supporting motion of various components of the switch assembly 100. These and additional features will be described in greater detail below.

The rotatable knob 102 may include a knob ring 110, a limit pin 114, a coupler 106, and a coupler cover 104. The rotatable knob 102 has an axis of rotation 101 around which one or more components of the rotatable knob 102 rotates. It is noted that the rotatable knob 102 may include a greater or fewer number of components without departing from the scope of the present disclosure.

The knob ring 110 may be any rotatable or twistable device, which may be rotated or twisted around the axis of rotation 101 of the rotatable knob 102. For example, the knob ring 110 is illustrated as being approximately circular and defining a coupler-receiving aperture 111. It is noted that while the knob ring 110 is shown as being circular, other shapes are also contemplated and possible (e.g., oval, egg-shaped, square, rectangular, etc.). The knob ring 110 may define a user engagement surface 112. In some embodiments, the user engagement surface 112 of the knob ring 110 may be textured in order to improve a user's ability to grip and twist the knob ring 110. Coupled to an interior facing surface 113 of the knob ring 110, opposite the user engagement surface 112, and offset from the axis of rotation 101, may be the limit pin 114. That is, the limit pin 114 extends from the interior facing surface 113 of the knob ring 110 at a location that is not a center of the knob ring 110, as depicted, for example, in FIG. 2C.

For mounting of the knob ring 110 to the frame 12, the assembly port 24 of the frame 12 may include a knob mounting recess 32, in which the rotatable knob 102 may be inserted. For example, the knob mounting recess 32 may define a main chamber sized and shaped to receive the knob ring 110 and allow rotation of the knob ring 110 within the knob mounting recess 32. Stated another way, the knob recess 32 is a recess formed in to the sidewall 22 of the frame 12. The knob recess 32 may be defined by separated raised walls 62 a, 62 b that extend from the sidewall 112 formed about the assembly port 24 and contiguous to the assembly port 24. The knob mounting recess 32 may be limited by a backstop wall 33, which may act to limit an insertion distance of knob ring 110 therethrough. The backstop wall 33 may be recessed into the sidewall 22, such that when assembled the knob ring 110 sits at least partially recessed into the sidewall 22.

Positioned adjacent to the backstop wall 33 may be a rotational limit slot 34 in which the limit pin 114 may be positioned (see also FIGS. 4A and 4B). The rotational limit slot 34 may define an arc of less than 360° (e.g., less than or equal to 180°, less than or equal to 90°, or the like) around the axis of rotation 101. Accordingly, as the knob ring 110 is rotated about the axis of rotation 101 of the rotatable knob 102, the limit pin 114 traverses the rotational limit slot 34. Once the limit pin 114 reaches an end of the rotational limit slot 34, the knob ring 110 is prevented from further rotation in that direction by the limit pin 114. The knob ring 110 may be rotated in an opposite direction until the limit pin 114 reaches a second end of the rotational limit slot 34. Stated another way, engagement of the limit pin 114 with the rotational limit slot 34 limits the angular rotation of the rotatable knob 102 about the axis of rotation 101 of the rotatable knob 102.

As noted above, the knob ring 110 may define a coupler-receiving aperture 111 that extends from the user engagement surface 112 to a stop wall 115. That is, the stop wall 115 may be inset into the knob ring 110. The coupler 106 may be any device configured to couple the knob ring 110 to the pin mechanism 160, as will be described in greater detail herein. For example, the coupler 106 may be a threaded fastener having a head 107 and a threaded shank 108. When assembled to the knob ring 110, the stop wall 115 of the coupler-receiving aperture 111 may be configured to engage with the head 107 of the coupler 106 to limit the insertion of the coupler 106 through the coupler-receiving aperture 111. The stop wall 115 may be of such a depth that the head 107 of the coupler 106 is completely positioned within the coupler-receiving aperture 111.

Referring to FIGS. 4A and 4B, which illustrate a cross-section of the protective case 10 along and parallel to the axis of rotation 101 of the switch assembly 100, formed within the stop wall 115 of the coupler-receiving aperture 111 may be a pass-through opening 116 to allow for the shank 108 of the coupler 106 to extend therethrough. The pass-through opening 116 may have a width larger than a width of the shank 108 to allow for both passage of the shank 108 and, insertion of a portion of a stem 162 of the pin mechanism 160. In particular, the pass-through opening 116 may be shaped to interlock with a stem 162 of the pin mechanism 160 such that rotation of the rotatable knob 102 causes rotation of the pin mechanism 160.

The coupler cover 104 may be any device for covering the head 107 of the coupler 106. For example, the coupler cover 104 may be a cap that may be pressed over the head 107 of the coupler 106 to cover or otherwise camouflage the head 107 of the coupler 106. The coupler cover 104 may include a locking flange 105 that interlocks with the knob ring 110, such as illustrated in FIGS. 4A and 4B. In particular, FIGS. 4A and 4B illustrate the locking flange 105 positioned within a locking recess 103 of the knob ring 110 adjacent to the stop wall 115. Stated another way, the locking flange 105 is sized and shaped to correspond to the locking recess 103. When in position within the locking recess 103, the locking flange 105 may be in contact with the stop wall 115.

Referring again to FIGS. 2A and 2B, the sidewall 22 may further define a sealant recess 35 for receiving an O-ring 120 or other sealant material. For example, inset further inward from the knob mounting recess 32 may be the sealant recess 35. The sealant recess 35 may have a width less than that of the knob recess 32. The sealant recess 35 may be sized and shaped for insertion of the O-ring 120 or other sealant material that may aid in preventing ingress of fluid into the protective case 10 through sidewall 22 or switch assembly 100. The sealant recess 35 may be of a depth such that the O-ring 120 or other sealant material is compressed between the knob ring 110 and a base 37 of the sealant recess 35. When assembled, the O-ring 120 or other sealant material may be positioned between and in contact with the knob ring 110 and the sidewall 22 (e.g., within the sealant recess 35) of the frame 12. The shank 108 of the coupler 106 may extend through a center of the O-ring 120 or other sealant material.

The sidewall 22 may define a through-passage 36 for one or more portions of the switch assembly 100 to extend. For example, the through-passage 36 may extend from the sealant recess 35 through the sidewall 22 to the interior side 68 of the sidewall 22. As illustrated in FIGS. 4A and 4B, when assembled the shank 108 of the coupler 106 may extend at least partially through the through-passage 36 to couple the knob ring 110 to the pin mechanism 160.

Referring now to FIG. 2C, the pin mechanism 160 may be any device engagable with the rotatable knob 102 and comprising a pin 168, which is offset from the axis of rotation 101 of the rotatable knob 102. For example, the pin 168 is spaced from the axis of rotation 101 and extends outwardly in a direction parallel to the axis of rotation 101. The pin mechanism 160 may include a stem 162 comprising a first end 163 and a second end 164, wherein the first end 163 of the stem 162 is engagable with the pass-through opening 116 of the knob ring 110. In embodiments, the first end 163 of the stem 162 may have a different cross-sectional shape than the second end 164 of the stem 162. For example, the first end 163 of the stem 162 may be shaped to substantially match a shape of the pass-through opening 116 of the knob ring 110, such that the first end 163 of the stem 162 may be nested within the pass-through opening 116 of the knob ring 110. The shape of the first end 163 of the stem 162 and the pass-through opening 116 may prevent rotation of the pin mechanism 160 relative to the knob ring 110. For example, the first end 163 of the stem 162 may be one or more straight wall sections that correspond to one or more straight wall sections of the pass-through opening 116 and prevent rotation of the first end 163 of the stem 162 within the pass-through opening 116. Such non-rotatable engagement may fix the pin mechanism 160 relative to the rotatable knob 102 such that rotation of the rotatable knob 102 rotates the pin mechanism 160.

In some embodiments, the first end 163 of the stem 162 and the second end 164 of the stem 162 may not have different cross-sectional shapes. For example, a non-rotatable engagement may be instead provided through friction (such as provided in a press-fit engagement) that prevents rotation of the pin mechanism 160 relative to the rotatable knob 102. In yet further embodiment, the action of tightening the coupler 106 may provide enough force to prevent rotation of the pin mechanism 160 relative to the rotatable knob 102.

A plate 166 may be coupled to the second end 164 of the stem 162 and the pin 168 may be coupled to and extend from the plate 166. The plate 166 of the pin mechanism 160 may extend past a width of the stem 162 to position the pin 168 further from the axis of rotation 101 of the rotatable knob 102. In other embodiments, the pin 168 may directly extend from the second end 164 of the stem 162.

Still referring to FIG. 2C, an interior side 62 of the sidewall 22 is depicted. Formed in the interior side of the sidewall 22, the assembly port 24 may further include one or more mounting recesses for mounting the pin mechanism 160 and slider body 170, described in greater detail below. The through-passage 36 may be sized to a dimension large enough to receive the stem 162 of the pin mechanism 160 therethrough and support rotational motion of the stem 162 about the axis of rotation 101. The through-passage 36 may open to a plate-receiving groove 38, which opens further into a slider groove 40. Stated another way, the plate-receiving groove 38 may be formed or otherwise inset into a back wall 41 of the slider groove 40.

Referring to FIGS. 4A and 4B, the stem 162 of the pin mechanism 160 may be advanced through the through-passage 36, through a center of the O-ring 120 or other sealant material, until the plate 166 of the pin mechanism 160 is positioned and contacted with the plate-receiving groove 38 to abut the through-passage 36. The O-ring 120 or other sealant material may form a fluid and/or airtight seal around the stem 162 of the pin mechanism 160. The first end 163 of the stem 162 may then be inserted into the pass-through opening 116 of the knob ring 110. The shank 108 of the coupler 106 may be engaged with an opening 169 (e.g., a threaded passage) formed within and extending into the first end 163 of the stem 162. The coupler 106 can be advanced into the opening 169 of the stem 162 until the head 107 of the coupler 106 engages the stop wall 115 of the knob ring 110. The coupler cover 104 may then be snapped into place over the head 107 of the coupler 106 to conceal the coupler 106. When assembled, the pin 168 of the pin mechanism 160 extends from the plate 166 into a volume of the slider groove 40 and into slot 174 of slider body 170.

The slider body 170 may be slidably disposed in the slider groove 40 and configured to slide along the slide path (e.g., along the X-direction of the coordinate axes depicted in FIGS. 3, 4A, and 4B) defined by the slider groove 40. The slider body 170 may be shaped to include the slot 174 in which the pin 168 of the pin mechanism 160 is positioned when the switch assembly 100 is assembled. The slot 174 may define a travel path (e.g., along a Z-direction of the coordinate axes depicted in FIGS. 3, 4A, and 4B) through which the pin 168 can travel. As illustrated, the travel path as defined by the slot 174 may be perpendicular to the axis of rotation 101 (e.g., extending along the Y-direction of the coordinate axes depicted in FIGS. 3, 4A, and 4B) of the rotatable knob 102. Furthermore, the travel path as defined by the slot 174 may be perpendicular to a slide path of the slider body 170 defined by the slider groove 40. For example, and as illustrated in FIGS. 4A and 4B, as the rotatable knob 102 is rotated about the axis of rotation 101, the pin 168 traverses the slot 174, which pushes the slider body 170 to slide along the slider groove 40 in a direction perpendicular to the axis of rotation 101 along the rotatable knob 102.

The slider body 170 may further also be shaped to include a switch recess 178 shaped to receive and selective contact a switch 52 of the electronic device 50 (illustrated in FIGS. 4A and 4B). For example, the switch recess 178 may engage the switch 52 such that movement of the slider body 170 causes the switch 52 to move between a first position, shown in FIG. 4A, and a second position (e.g., a silencing position and a sound-on position where the switch 52 is a silencing switch 52), shown in FIG. 4B. For example, the slider body 170 may be moved into contact with a first portion 54 of the switch 52 to urge the switch 52 into a first position (e.g., as shown in FIG. 4A). The slider body 170 may be moved into contact with a second portion 56 of the switch 52 to urge the switch 52 into a second position (e.g., as shown in FIG. 4B).

To retain the slider body 170 within the slider groove 40, the slider body 170 may have one or more locking flanges. For example, the slider body 170 may include a first locking flange 173 coupled to and extending along a first edge 175 of the slider body 170. The first locking flange 173 may have a reduced thickness relative to a thickness of the first edge 175 of the slider body 170. The first locking flange 173 may be integral with the slider body 170 or a separate component therefrom. The first locking flange 173 may be continuous along the first edge 175 or may be discontinuous along the first edge 175. For example and as illustrated, the first locking flange 173 may not be continuous across a base of the slot 174.

The slider groove 40 may have a channel 42 formed at the base of the slider groove 40. When assembled, the first locking flange 173 may be inserted into the channel 42 and slidable along the channel 42. The first edge 175 of the slider body 170 may positioned over and in contact with a base surface 44 of the slider groove 40.

The slider body 170 may include a second locking flange 177 along a second edge 176 of the slider body 170 opposite the first edge 175. The second locking flange 177 may have a reduced thickness relative to a thickness of the second edge 176 of the slider body 170. The second locking flange 177 may be integral with the slider body 170 or a separate component therefrom. The second locking flange 177 may be continuous along the second edge 176 or may be discontinuous along the second edge 176. In some embodiments, the switch recess 178 may have an inset depth greater than a thickness of the second locking flange 177.

A locking mechanism 150 may be provided to engage the second locking flange 177 so as to lock the slider body 170 into the slider groove 40. That is, the locking mechanism 150 may be arranged about the slider body 170 to restrict motion of the slider body 170 in a direction transverse to the slide path as defined by the slider groove 40. To facilitate locking of the slider body 170 within the slider groove 40, the locking mechanism 150 may comprise an elongate body 151. Referring to FIG. 3 , when assembled, the elongate body 151 may extend over the second locking flange 177 to prevent the slider body 170 from becoming dislodged from the slider groove 40. The elongate body 151 may have a reduced thickness over the switch recess 178, to allow for insertion of the switch 52 passed the elongate body 151 and into the switch recess 178.

At either end of the elongate body 151, may be locking prongs 152 a, 152 b, configured to mate with mating apertures 53 a, 53 b formed within the frame 12, illustrated in FIG. 2C. Stated another way, a first locking prong 152 a may extend from a first end of the elongate body 151 and a second locking prong 152 b may extend from a second end of the elongate body 151. The first mating aperture 53 a may extend into the frame 12 on one side of the assembly port 24 and the second mating aperture 53 b may be extend into the frame 12 on a second side of the assembly port 24. The locking prongs 152 a, 152 b may be pressed into the mating apertures 53 a, 53 b to mount the locking mechanism 150 to the frame 12. The locking prongs 152 a, 152 b may engage the mating apertures 53 a, 53 b in a press fit to ensure a secure engagement between the locking prongs 152 a, 152 b and the mating apertures 53 a, 53 b. In some embodiments, the mating apertures 53 a, 53 b may include pressure release slits 54 a, 54 b, to allow for escape of air when mating the locking prongs 152 a, 152 b with the mating apertures 53 a, 53 b.

Referring now to FIGS. 4A and 4B, operation of the switch assembly 100 will now be described. FIG. 4A illustrates an electronic device 50 positioned within the protective case 10 to provide an electronic device assembly 200. That is, the protective case 10 provides a protective covering to the electronic device 50. Referring to FIGS. 1A and 1B, the front portion 14 couples to the back portion 16 of the frame 12 to encapsulate the electronic device 50 within the protective case 10 within cavity 11. The switch 52 of the electronic device 50 is positioned in a first position (e.g., an active position) and at least partially positioned within the switch recess 178 of the slider body 170. Accordingly, when the slider body 170 moves, the slider body 170 is selectively contacted with the first or second portions 54, 56 of the switch 52. The contact between the slider body 170 and the switch 52 causes the switch 52 to move from the first position to the second position shown in FIG. 4B.

To cause the slider body 170 to move the switch 52 from the first position to the second position, a user may contact the contact surface 112 of the knob ring 110, and twist the knob ring 110 about the axis of rotation 101 in a first direction (e.g., a clockwise direction). Such twisting causes the pin mechanism 160 to travel the pin 168 within the slot 174 of the slider body 170 in a first direction and move the slider body 170 toward contact with the first portion 54 of the switch 52 to urge the switch 52 to a first position. That is, movement of the pin 168 imparts a force to the slider body 170 surrounding the slot 174, causing the slider body 170 to move along the slide path and the pin 168 to move along the slot 174. As the slider body 170 moves, the force is transferred to the switch 52, which causes the switch 52 to move with the slider body 170 to the second position shown in FIG. 4B.

To move the switch 52 back to the original position shown in FIG. 4A, a user may engage the contact surface 112 of the knob ring 110 and twist the knob ring 110 about the axis of rotation 101 in a second direction (e.g., a counterclockwise direction). The opposite twisting direction causes the pin mechanism 160 to traverse the pin 168 along the slot 174 in opposite second, opposite direction to move the slider body 170 toward contact with the second portion 26 of the switch 52 to urge the switch 52 to a second position. That is, the pin 168 applies a force to the slider body 170 to move the slider body 170 and the switch 52 back to the second position depicted in FIG. 4A.
